Humidity Control for Pneumatic Powder Conveying
Humidity / Moisture Control is a critical element for various forms of powders such as fine salt, detergents, flour, powdery foods, calcium phosphate, baking powder, wheat starch, plastics resin etc. Pneumatic conveying as a means of powder conveying system is widely used in many powder processing operations such as in handling transfer of food powders, flour in a mill, bakery or confectionery.
Due to the stickiness nature of the hygroscopic powders, they get stuck into nozzles, conveying belts and mixing machines leading to increased maintenance time and bad hygiene.
Stickiness – Powder gains properties of adhering or sticking to a surface and get stuck into conveying belts causing bad hygiene which ultimately leads to deteriorating of product quality.
Cluster formation – Due to excess moisture similar particles of powder gather closely together forming buildups inside the mixing machine and causing blockages in free flow of powder.
Lump formation – A large piece of powder sticks together without a definite shape causing obstruction in the nozzle passage and increasing the maintenance time.
Caking – Moist environment forces powder to change into a solid mass which leads to increase in product wastage and slowing down of production process.
Food powder processing
In order to retain quality of powdery foods, they need to be dried at low temperatures.

Hygro Tech Engineers having a complete solution to treat the moisture problems with Hygro Dehumidifiers & drying chambers for all powder conveying, packing, storage

Improper drying can damage the product. Products needs to be dried to recommended moisture content level & optimum drying is difficult given the variability of the product being dried and thus, proper understanding of the drying requirement and process is extremely important. Drying criteria vary from product to product, given the unique characteristics/requirement of different products. Some products are more temperature sensitive than others and hence, require special type of drying. Products, generally have surface moisture (present free on the product surface and can be removed easily) and inherit/core moisture (which is difficult to remove) and require special drying techniques. Drying is also often the largest energy consuming process, and the process needs to be understood to effectively to rationalize energy needs. It is important to understand the drying techniques and technologies to reduce spoilage and enhance the quality of the product.
Hygro provides complete drying solution with HYgro products in applications like food drying, Pharmaceutical, mechanical industry, Aviation, Leather, spices, tea & coffee drying, film drying, parachute drying, investment casting drying etc...

DESICCANT ROTOR
The desiccant rotor is a high capacity desiccant media captivated in a circumference rim with radial spokes. The spokes attach to a central hub with integral sealed ball bearings. The sealed bearings ride on a solid center shaft. The rotor is held in place with a lock ring on each side the desiccant material, usually a silica gel impregnated into a support. This looks like a honeycomb, which is open on both ends. Air passes through the honeycomb passages, giving up moisture to the desiccant contained in the walls of the honeycomb cells. The desiccant structure is formed into the shape of a wheel. The wheel constantly rotates through two separate air streams. The first stream, called the process air. Is dries by the desiccant. The second air stream, called reactivation or regeneration air, is heated. It dries the desiccant.

HYGRO DEHUMIDIFIER ADVANTAGES
The Dehumidifier Manufactured by Hygro Tech is non cyclic, rotary type and removes the moisture by process of continues physical adsorption.
The desiccant used by Hygro Tech is non toxic, non flammable with maximum moisture removal Capacity
Hygro Dehumidifier can maintain Relative humidity (RH) as low as 1% regardless of ambient conditions.

moisture during PCB assembly can increase the number of failures during assembly, and decrease the circuit assemblies and its life.
Exposure to high moisture during Printed Circuit Board (PCB) assembly and manufacturing, leads to
Microscopic corrosion
Adhesion failures
Surface defects
Decreased performance of the circuit board.
Increase electrical resistance
Decrease capacitance.
Hygro Desiccant Dehumidifiers provide the ideal low humidity environment in the manufacturing, assembly and storage of these precision, high quality electronic Printed Circuit Boards since they are capable of maintaining RH as low as 1% or even lower at a constant level, regardless of ambient conditions.

Humidity Control for Turbine Storage
Turbines are indispensable for power generation and like work. It is necessary to maintain Turbines and other equipment in prime condition while in operation and during storage. This enables smooth running of the turbines and also ensures that they are capable of going ‘on-line’ immediately post storage.
Moisture however plays havoc with Turbines, Power Generators, Boilers, Condensers etc. These equipment begin to rust and corrode while in storage or while in operation.
If the relative humidity of the area where expensive equipment is stored can be restricted below 40%, then all equipment like generator, turbines and their components can be maintained in well -preserved condition for immediate activation whenever required. Hygro Dehumidifiers prevents corrosion, mold and mildew growth and prevents deterioration of equipment.
